For others – we offer the Randakk High Performance Fuel Filter with sizes to fit virtually any carbureted motorcycle. Details here.

Problems with Aftermarket Float Valves

I get lots of emails like this one: 

“I purchased four “Napco Carb rebuild Kits” in addition to some parts from you like plenum seals, etc. I probably should have purchased your Master Kit. Anyway, 2 of the Napco float valves would not seat properly resulting in a lot of frustrating problems. With your recommendation, I cleaned and put the original Honda float valves back into the carbs. Problem Solved. Thanks!”Lee Korb – Raleigh, NC
